This is how I add nutrients to my indoor cannabis grow room! Very simple and easy to do.Mix with one gallon of Reverse osmosis water. I use Botanicare line of nutrients. Easily found in most hydroponic stores or amazon.
Recipe for 1 Gallon of Reverse Osmosis water:
1 teaspoon = 5ML (cal-mag)
1 tablespoon = 15ML (veg grow nutes)
1/2 teaspoon = 2.5ML (snow storm ultra)
Reduce your nutes by 15% when adding multiple nutrients is important so you don’t get nutrient burn on your leaves and they stay a light but beautiful green!
